What is the role of cellular reproduction in maintaining genetic continuity

Genetic continuity describes the fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell. It also describes the fact that when two sexually reproducing organisms mate, the offspring have the same number of genes as the parent organisms. Genetic continuity ensures that new cells or organisms have enough genes to survive. It is a way of preserving the genetic information across generations. A lack of genetic continuity results in diseases.
